"Blei" 'known 'that I FRANZ Promesuo ject of the IGerizisn' mperor, residing at Munich, Germeny, lieve invented, lcertain new che. useillmprovements in Electric- CircuitCoi'itroilers, of which the following is a specification.

My invention relates to' electric circuit controllers generally', aiid has particular reference to an automatically operating makeaiil-breal .clerics for the lightirig circuit used.- in connection With electric display signs and the like -i The principal object of the invention is to provide o mske-end-breek alevice, which may be cheaply constructed owing to its simplicit)T of eteil and arrangement, aiicl which will operate reliably without requirfrequeiit attention. 1

The iioventioii includes e. stationary supimrt, suoli as an insulating disk, to which e terminals of the lighting circuit or eirzoits src connected; :fi rotatable mem `er the contact rocker esigne :for coatiff Witli lie teriiiiiisls on the stationl means for rotatirig the ro est to the support,

The a carries a series ci terminals E to which the ends of the Wires Z1 or the lightu ley reference srs-t ing circuit, are attached. The terminals fi are arranged in a circuler series near the periphery ofi' the disk l?, emi; each termiiiel has its head preferably beveled or inclined et 252 as shown.
